  ORNITHOLOGICAL 
  NOTES 
  FROM 
  NORFOLK 
  AND 
  THE 
  

   EAST 
  COAST 
  OF 
  ENGLAND 
  FOR 
  1903.

  As 
  usual, 
  " 
  Norfolk 
  Notes 
  " 
  refer 
  largely 
  to 
  migration. 
  This 
  

   is 
  the 
  chief 
  'subject 
  which 
  impresses 
  itself 
  on 
  the 
  mind 
  of 
  any 
  

   naturalist 
  living 
  on 
  the 
  east 
  coast, 
  and 
  it 
  is 
  a 
  strange 
  sight 
  in 
  

   autumn 
  to 
  watch 
  for 
  the 
  birds 
  which 
  have 
  come 
  in 
  during 
  the 
  

   night, 
  and, 
  if 
  there 
  be 
  a 
  west 
  wind, 
  for 
  those 
  which 
  will 
  arrive 
  

   in 
  the 
  morning. 
  In 
  this 
  connection 
  Mr. 
  W. 
  Eagle 
  Clarke, 
  during 
  

   1903, 
  has 
  made 
  an 
  experiment 
  on 
  a 
  " 
  floating 
  light," 
  which, 
  

   although 
  not 
  on 
  our 
  coast, 
  is 
  well 
  worth 
  calling 
  attention 
  to. 
  

  

  Mr. 
  Eagle 
  Clarke 
  remained 
  on 
  the 
  Kentish 
  Knock 
  lightship, 
  

   off 
  the 
  Essex 
  coast, 
  from 
  Sept. 
  17th 
  until 
  Oct. 
  18th, 
  and 
  it 
  is 
  

   instructive 
  to 
  compare 
  his 
  observations 
  ('Ibis,' 
  1904, 
  p. 
  112) 
  with 
  

   those 
  made 
  during 
  the 
  same 
  period 
  by 
  observers 
  on 
  the 
  coasts 
  of 
  

   Norfolk 
  and 
  Suffolk. 
  Mr. 
  Clarke 
  considered 
  that 
  the 
  day 
  migra- 
  

   tions 
  equalled 
  those 
  observed 
  during 
  night, 
  but 
  in 
  Norfolk 
  they 
  

   are 
  probably 
  far 
  inferior, 
  except 
  in 
  the 
  case 
  of 
  the 
  Corrida, 
  which 
  

   are 
  day 
  migrants 
  ; 
  but 
  Mr. 
  Clarke's 
  statement 
  shows 
  how 
  much 
  

   there 
  is 
  still 
  to 
  be 
  learnt. 
  He 
  is 
  of 
  opinion 
  that 
  immense 
  num- 
  

   bers 
  of 
  birds 
  are 
  killed 
  by 
  contact 
  with 
  light-vessels 
  which 
  show 
  

   a 
  white 
  light, 
  and 
  that 
  many 
  of 
  the 
  migrants 
  avoid 
  the 
  force 
  of 
  

   the 
  wind 
  by 
  flying 
  close 
  to 
  the 
  surface 
  of 
  the 
  sea, 
  which, 
  in 
  the 
  

   case 
  of 
  the 
  Sky-Lark, 
  agrees 
  with 
  what 
  I 
  have 
  observed 
  off
